Rebrand pbwowext as a generic style enhancement extension

[avandenberghe]

Summary

pbwowext has evolved beyond its original pbWoW3-specific scope. It now provides generic style enhancement features (top-bar, custom logo, video background, fixed background, header links, donate block styling) that work across multiple styles including PBTech, Avathar, and others.

The extension should be rebranded to reflect this — both in name and in code structure.

Scope

• Rename extension: paybas/pbwowext → avathar/styleext (or similar)
• Rename vendor namespace: paybas\pbwowext → avathar\styleext
• Rename DB table: pbwowext_config → new table name
• Rename ACP module: update module titles, language keys (PBWOW_* → generic naming)
• Rename cache key: pbwow_config → new key
• Update composer.json: new name, description
• Migration: add migration to rename DB table, preserve existing config
• Language files: rename all PBWOW_* keys across 14 translations
• CSS files: rename pbwowext.css references
• Template events: keep top_bar_links_before/after event names (or deprecate + add new ones)
• Body class: pbwow-ext → generic class name
• Repository: new repo under avatharbe org

Considerations

• Need a phpBB migration to rename the DB table so existing installs don't lose config
• The paybas vendor directory will change to avathar — users will need to disable old, install new
• Consider whether this should be a clean break (new extension) or an in-place rename with migration
• The donate block CSS/images are site-specific (avathar.be) but the container feature is generic

• pbwowext's modify_ads_code event listener and get_ads_index_code() have been removed
• Donate CSS/images remain in pbwowext as style-specific presentation
